Ash and his friends arrive in a town where a Chinchou festival is apparently taking place. Every year, the Chinchou embark on a migration to breed at the end of their journey. The island town is essentially the Chinchous breeding ground. Because the Chinchoud antennae glow so beautifully during mating, the residents hold a festival annually. As a Water-type Pokémon trainer, Misty finds this fascinating.
